IPv4 Vs IPv6, the world of networking has changed a lot in the past few years.
So, How IPv4 Vs IPv6 are different?
IPv4, or Internet Protocol version 4, is the fourth iteration of the Internet Protocol. Since the early 1980s, it’s been the most widely used protocol for networking. There are only 4.3 billion unique IP addresses in IPv4 because it’s a 32-bit addressing system. However, as the internet grows, more is needed, so IPv6 was developed.
IPv6, or Internet Protocol version 6, is the sixth iteration of the Internet Protocol. It is a 128-bit addressing system that can provide multiple unique IP addresses. IPv6 offers 340 undecillion unique addresses, which is enough to support the growth of the internet for the foreseeable future. Additionally, IPv6 offers other benefits, such as improved security, auto-configuration, and better support for mobile devices.
We’re still using IPv4, which is slowing down the transition to IPv6. IPv4 addresses are running out, so IPv6 is taking over. Many organizations have already switched to IPv6, which is on its way to becoming the standard.
There are a lot of advantages to IPv6 over IPv4, including better mobile support, improved security, and auto-configuration. As the internet changes, IPv6 is designed to support future technology growth.
IPv4 will be replaced with IPv6 soon. Although IPv4 still dominates, IPv6 has evolved due to IPv4’s limitations. With IPv6, mobile devices will work better, security will be improved, auto-configuration will be easier, and the address space will be bigger.
Differences between IPv4 Vs IPv6
An IP address system that’s reliable and secure is more important than ever as the world relies more on the internet. Since IPv4 has been around for more than 30 years, it’s become clear that it has limitations when compared to IPv6.
Globally, IPv4 is the most popular IP address system. Because it’s 32-bit, it’s able to handle 4.3 billion IP addresses. With so many devices needing IP addresses (like smartphones and tablets), IPv4 addresses are running out fast.
IPv6, on the other hand, was a newer IP address system introduced in 1998. It is a 128-bit system, meaning it can provide up to 340 undecillion unique IP addresses (340 followed by 36 zeros).
IPV4 has 20-60 bytes header, whereas IPV6 has 40 bytes
A significant improvement over IPv4 ensures that there will be enough IP addresses for all devices, now and in the future.
Network traffic is another major difference between IPv4 and IPv6. IPv4 uses Network Address Translation (NAT) to allow multiple devices to share a single IP address. It can cause issues with certain internet applications, such as peer-to-peer file sharing and online gaming. IPv6, on the other hand, uses a unique IP address for every device, eliminating the need for NAT and allowing for more efficient and reliable network traffic.
Another key difference between IPv4 Vs IPv6 is their security features. IPv6 includes built-in security features, such as IPsec, which provides authentication and encryption for network traffic. It helps to ensure data security and privacy, even when traveling on public networks.
While IPv4 has served us well for over 30 years, it clearly has its limitations. IPv6 offers significant improvements in available IP addresses, network traffic efficiency, and security features. As more and more devices connect to the internet, a reliable and secure IP address system becomes more crucial. IPv6 provides the solution to this problem and is already adopted by many organizations around the world.
